Thanks everyone for your help !! I've looked at various pictures of
arum maculatum on the net and it looks as if it matches. The photo I've
linked was one I found in a plant guide book and which I scanned and
not an actual photo that I took. The photo was of a spring wood scene
with cyclamen and I noticed the arum in the corner. It was the only pic
I could find of it. As I said earlier I have some growing in the back
of my garden and once it spikes berries should I be worried for my cat
? If it is poisonous for humans will it affect the neighbourhood cats,
squirrels, badgers, etc etc ?? I'm concerned for catty as it has a
tendancy to gobble anything that looks vaguely interesting.
Thanks again for all your help you have all been absolutely fantastic
in your efforts !!!

ps: Has anyone used the plant in their own garden to create a woodland
effect ? I have an area with a fern and some foxgloves and am thinking
of maybe getting some for that part of the garden.
